Full question →mediummultiple choiceObjective-mapped
A security team uses Microsoft Sentinel. They want to create a custom analytic rule that triggers an incident when more than 10 failed Azure Active Directory sign-ins occur from the same source IP address within any 5-minute window. Which type of rule should they use?
Answer choices
Why each option matters
Good practice is not just finding the correct option. The wrong answers often show the exact trap the exam wants you to fall into.
A
Best answer
Scheduled query rule
Scheduled query rules run on a schedule (e.g., every 5 minutes) and support aggregation over time windows. They are ideal for counting events and setting thresholds.
B
Distractor review
Near-Real-Time (NRT) rule
NRT rules run every minute but have a short lookback (typically 10 minutes) and are designed for single-event detection, not for counting over a fixed window.
C
Distractor review
Fusion rule
Fusion rules use advanced machine learning to correlate multiple alerts into incidents, not for simple threshold-based counting.
D
Distractor review
Anomaly rule
Anomaly rules use machine learning to detect deviations from baseline behavior, not for hard thresholds like a count of 10.
Common exam trap
Common exam trap: answer the scenario, not the keyword
Many certification questions include familiar terms but test a specific constraint. Read the exact wording before choosing an answer that is generally true but wrong for this case.
Technical deep dive
How to think about this question
This question should be treated as a scenario, not a definition check. Identify the problem, the constraint and the best action. Then compare each option against those facts.
KKey Concepts to Remember
- Read the scenario before looking for a memorised answer.
- Find the constraint that changes the correct option.
- Eliminate answers that are true in general but not in this case.
- Use explanations to understand the rule behind the answer.
TExam Day Tips
- Underline the problem statement mentally.
- Watch for words such as best, first, most likely and least administrative effort.
- Review why wrong options are wrong, not only why the correct option is correct.

FAQ
Questions learners often ask
What does this AZ-500 question test?
Read the scenario before looking for a memorised answer.
What is the correct answer to this question?
The correct answer is: Scheduled query rule — Microsoft Sentinel offers several rule types: Scheduled query rules run periodically (e.g., every 5 minutes) and can aggregate data over a time window. Near-Real-Time (NRT) rules run every minute and have a lookback period, but they are not designed for large aggregation windows like 5 minutes with a count threshold. Fusion and Anomaly rules are machine learning-based and not suitable for this deterministic logic. A Scheduled query rule configured to run every 5 minutes with a query that groups by IP address and counts failed sign-ins, using a threshold of 10, is the correct approach.
